Printing 2D array in full ignores edited values, prints initialised values - c++

Question

beginner to C++ and attempting a dungeon crawler beginner task, upon testing one of the classes I found that printing the 2D array works, however if it is edited and printed, it resets and prints original values it was initialised with.
InitGrid is used to initialize the array.
class MAP
{
public:
/*
Difficulty used in number of enemies and traps created.
1-5 Difficulty
| 1 - Too easy | 2 - Easy | 3 - Normal | 4 - Hard | 5 - Insane |
*/
int Difficulty = Hard; //### Temporary, user selection needs implemented ###
int SpawnPos;
int TPosX; //Treasure Postion, used to checkwinstate.
int TPosY; //Treasure Postion, used to checkwinstate.
char Grid[MAPHeight][MAPWidth];
void InitGrid()
{
for (int y = 0; y < 9; y++) //Row loop
{
for (int x = 0; x < 14; x++) //Column loop
{
Grid[y][x] = { '.' };
}
}
}
void PrintMap()
{
for (int y = 0; y < 9; y++) //This loops on the rows.
{
for (int PrintX = 0; PrintX < 14; PrintX++) //This loops on the columns
{
cout << Grid[y][PrintX] << " ";
}
cout << endl;
}
}
void GenerateEnemies()
{
for (int i = 0; i < Difficulty; i++)
{
int TotEnemies = (Difficulty * 1.5);
for (TotEnemies; TotEnemies == 0; TotEnemies--)
{
int x = rand() % (MAPWidth - 1);
int y = rand() % (MAPHeight - 1);
if (Grid[y][x] == '.')
{
Grid[y][x] = '#';
}
else
{
GenerateEnemies();
}
}
}
}
// Generate Enemies
void GenerateTraps()
{
for (int i = 0; i < Difficulty; i++)
{
int TotTraps = (Difficulty * 1.5);
for (TotTraps; TotTraps == 0; TotTraps--)
{
int x = rand() % (MAPWidth - 1);
int y = rand() % (MAPHeight - 1);
if (Grid[y][x] == '.')
{
Grid[y][x] = 'T';
}
else
{
GenerateTraps();
}
}
}
}
void GenerateTreasure()
{
int x = rand() % MAPWidth;
int y = rand() % MAPHeight;
/*
Randomly selects spawn location
uses tmp variables to overwrite
that grid location.
*/
if (Grid[y][x] == '.')
{
Grid[y][x] = 'X';
}
else
{
GenerateTreasure();
}
TPosX = x;
TPosY = y;
}
};
//PLAYER CLASS
class PLAYER : public MAP
{
public:
int Health = (Difficulty * 1.5);
int PPosX;
int PPosY;
char Direction; //Use cin to get user input after map is updated, used in switch case to move player.
void GenerateSpawn()
{
int x = rand() % (MAPWidth - 1);
int y = rand() % (MAPHeight - 1);
/*
Randomly selects spawn location
uses tmp variables to overwrite
that grid location.
*/
Grid[y][x] = 'P';
PPosX = x;
PPosY = y;
}
void AllowMove(int y, int x)
{
if (Grid[y][x] == '.')
{
Grid[y][x] = '#';
}
else if (Grid[y][x] == 'X')
{
//GameWin();
}
else if (Grid[y][x] == '#')
{
//DamagePlayer();
}
else {}
}
void MovePlayer()
{
switch (Direction)
{
case 'w':
{
int x = PPosX;
int y = (PPosY + 1);
void AllowMove(int y, int x);
}
break;
case 'a':
{
int x = (PPosX - 1);
int y = PPosY;
void AllowMove(int y, int x);
}
break;
case 's':
{
int x = (PPosX);
int y = PPosY;
void AllowMove(int y, int x);
}
break;
case 'd':
{
int x = (PPosX + 1);
int y = PPosY;
void AllowMove(int y, int x);
}
break;
default:
cout << "invalid character, try again." << endl;
Sleep(5000);
//Call function to retry
}
}
};
//######### End #########
//Main Function
int main() {
srand(time(NULL)); //Used to seed rand() values.
SetConsoleTitle(TEXT("Dungeon Crawler"));
//Objects
MAP Map;
PLAYER Player;
Map.InitGrid();
Player.GenerateSpawn();
//Map.GenerateTreasure();
//Map.GenerateEnemies();
//Map.GenerateTraps();
Map.PrintMap();
cout << endl;
}
However, when I run these, I get the following image:
I've attempted debugging in visual studio using breakpoints and at some point it does set the grid value to 'P' but I couldn't find where I gets 'reset' for lack of a better term.

Answer 1

char Grid[MAPHeight][MAPWidth]; needs to be moved outside of the class as a global variable. Currently as the PLAYER class inherits from the MAPS class, when GenerateSpawn() edits the Grid that is created specific to the object linked to PLAYER.
When it is a global variable, it is separate, then when edited by GenerateSpawn() and called by void PrintMap() they both use the same Grid.
That way when it is printed to console it correctly prints out the map.
Answered my own question in case someone else stumbles upon this.
